I got her from Piloted Sky Golem, and managed to attack too. Guess what? She turned back into another Piloted Sky Golem! I was hoping she would drop out of it again, but the game ended before she could eject.

This card is actually very strong because the only bad outcomes are Corrupted Seer and Big-Time Racketeer, everything else is as good or better than a 3/5 and you can use its Health to trade first instead of hitting face immediatly.

in hearthstone , they can , same idea like you can be holy priest as undead forsaken in world of warcraft , or druid play Imp Master or Flesheating Ghoul

You can be holy priest as a Forsaken because the lore support it, if you played burning crusade or older there are several quest lines in forsaken-priest that denotes that you feel you burn inside every time you cast a holy spell, and how anxious you feel being constantly surrounded by holy light.

And those cards were made neutral for a reason <.< the point is to support archetypes not just break lore "for the lulz" like this card, wich can be ANY of the MANY races with shamans in their races (more than just the playable, where are the furbolg's? The taunka's? The naga's? but nah, lets add a random (may-be druid) night elf for a shaman card :P
